Constant lag, app crashes and sd card woes

The title says it all... This hunk of junk lags when opening apps, at times refusing to open apps at all. Sometimes the apps hang up and stop responding and I'm greeted with the would you like to wait or close prompt. There isn't any specific app, it's all. The SD card has a mind of its own and decides it wants to unmount on its own accord. Going to try the restore tool when I get home... If that doesn't work I'm going to rma this piece of poop. It seems the QC has gone down for Lenovo owned Motorola. My Moto G 2015 with 1gb of ram preforms better. My Nexus 6 runs laps around it. I'm so frustrated.
